L. FERENCI CIGAR CELLOPHANE ENVELOPE END CRIMPING DEVICE Filed June 20, 1930 uulll @WTTORNEY Patented Feb. 27, 1934 PATENT OFFICE CIGAR CELLOPHANE-ENVELOPE END-CRIMPING DEVICE Lester Ferenci, Brooklyn, N. Y., asslgnor to International Cigar Machinery Company, a corporation of New Jersey Application June 20, 1930. Serial No.. 462,599

4 Claims.

This in.'ention relates to improvements in closing Cellophane" envelope ends, and particularly to a cigar envelope having a novel closed end and a method and apparatus for closing the same.

The principal object of this invention is to provide a simple and inexpensive apparatus and process for forming the end closure of a transparent Cellophane envelope for articles. To this end it is an object of the invention to provide a method and apparatusfor making such an end closure in which the same operation which crimps the end of the envelope will give them a set or curl which will turn up the projecting crimped material, so that whe viewed from one side as when packed in boxes the packages formed will present a neat appear Another object is to dispense with the end flap or tongue folding operation hitherto used for bending backthe longitudinally projecting flap which results from ordinary crimping.

With these and other objects not specifically mentioned in view, the invention resides in certain methods, apparatus, and cigar envelopes which will be hereinafter described and then specifically set forth in the claims hereunto appended.

In the accompanying drawing, which forms a part of this specification and in which like characters of reference indicate the same or like parts:

Fig. 1 is a side elevation 01' the crimping device with the crimping blocks in open position on one end of the enveloped cigar;

Fig. 2 is a similar view with the crimping blocks in closed position;

Fig. 3 is a similar view after the crimping' blocks have returned to open position, showing how the crimped end ofthe envelope curls up after being released;

Fig. 4 is a side elevation of an enveloped-cigar having its ends crimped and curled by the improved crimping device; and

Figs. 1A, 2A, and 3A are end elevations of the cigar envelope corresponding to steps shown in Figs. 1, 2, and 3, respectively, the envelope in i Fig. 1A being shown already side tucked by any plication of heat to one face thereof to provide a novel cigar envelope having curled end flaps having a plurality of crimps. All the apparatus that is essential to the practice of the invention in its simplest form is a pair of cooperating relatively movable crimping blocks having interfitting corrugations on their operating faces, whereby to form the crimped and curled flaps. In the method illustrated an envelope E of Cellophane" or like transparent cellulosic material is wrapped about a cigar C with the ends E of the envelope projecting beyond the end of the cigar in the manner shown in Fig. 1. The crimping blocks 4 and 5 of the crimping device are then brought together on the top and bottom sides of the overhanging material after the vertical sides have been inwardly tucked by any suitable means such as that disclosed in the patent to Wheeler, No. 1,899,174, granted Feb..28, 1933. These blocks have interfitting corrugations 7 and 8 running transversely of their operating surfaces which serve to crimp the projecting material as shown in Fig. 3. heated by means of a heater 6, while the block 5 remains relatively cool. It has been found that this differential heating of the upper side of the overhanging material relative to the lower side results in a curling of the material which brings the material into the position and shape shown in Fig. 3, without requiring any additional folding operation. So curled, the cigar when placed with curl down presents a neat appearance, without further manipulation. The blocks may be given their crimping and retracting movements by any suitable means such as thatshown in the patent to Wheeler, No. 1,899,174, granted Feb. 28, 1933, in which the blocks 4 and 5 may be readily substituted for the mold blocks therein disclosed. While applicants improved method and apparatus has been shown and described in connection with one end of the cigar envelope, it is understood of course that identical operations are performed at the other end of the cigar envelope.

What is claimed is: c 1. A crimping device for closing the ends of cigar envelopes, comprising a pair of cooperating relatively movable crimping blocks provided with a plurality of interengaging corrugations on their operating faces, one only of said blocks being heated, whereby to form a curled flap having a plurality of crimps on the ends of the envelope.

2. The process of closing the ends of cigar envelopes which comprises forming a plurality Block 4' is flap, and means for causing the corrugated end flap of the envelope to curl.

'4. The method of sealing the ends of "Cellophane" cigar envelopes having plications in the projecting end portion of the envelope which comprises curling said end portion and corrugati'ng the same including the plications thereof in a plurality of places to seal said end.
